3. Microsoft Exchange Server Microsoft Exchange Server is
accounted as the most successful, secure mailing server and a
powerful organizer developed by Microsoft. It is basically server
side software which is used to manage a workgroup, enterprise or
home users mailbox. It is not only an on premise software but with
the help of Outlook Web Access synchronization; clients could
manage their day to day emails, tasks and messages easily anywhere.
Exchange Server is extensively used by Enterprise users as the
server allows secure mailing, maintains a physically accessible
database and personal mailbox management.
5. Dirty Shutdown Dirty Shutdown is a state which occurs only
when the information store doesnt get closed properly.This might be
due to power failure, connection failure or any other disaster that
leads towards this issue. Dirty shutdown cannot be considered as
sign of damaged database, instead it is just that the Exchange
database was not closed properly and leads towards Exchange data
file EDB and STM Corruption. How do you know that Dirty Shutdown
state has occurred? Use ESEUTIl to detect data-integrity, repair
corrupt file portions and helps to defragment the database, but
only when the database is offline.
6. Determining Dirty Shutdown State Use ESEUTIl /mh to
determine the log file and checks that the database is in the clean
state or not (could be accessed using CMD->C:Program
FilesExchSrvrBin and then type in eseutil /ml )
7. Solution? With the help of /mh utility we determined that
Dirty Shutdown state is the cause of error or not.The next step is
to repair the damaged data using repair and then defragmentation
utility. ESEUTIL /r help recover from Dirty shutdown error, by
scanning the bad sec and then fixes those errors.
8. Corrupt EDB Mailbox Files Malfunctions such as hardware
failure, System/Server failure, dirty shutdown or any other type of
disaster causes the mailbox files such as priv1.edb, pub.edb to get
corrupted. This issue results in inaccessibility to the mailbox
data due to corrupt mailbox file
9. Recovering from the issue : Fixing Corrupt Mailbox requires
users discretion as human error could lead to permanent loss of
data. Utilities such as ESEUTIL / ISINTEG could be used to perform
local diagnosis, repair and defragmentation.These procedures are
helpful in case of normal level of corruption, but in case of high
corruption trusted third party tools should be preferred. For

10. Checksum Error Exchange databases on page level are just
set of numbered pages where data is read and written one at time
.Checksum tests are performed for each page to check for
moderations and alterations .Now when we face a checksum mismatch
error this indicates that : The page details arent getting matched
as they were supposed to be. The page number doesnt match with the
actual page location. Hardware or firmware issues trigger checksum
errors.
11. Getting Rid off Checksum Error Restore Data from a hot
backup:A recent backup of the Exchange database would restore the
data back to its original location, hence eliminating an error. Use
ESEUTIL/ISINTEG commands to repair, debug and defragment EDB
Files.
